Patented Aug. 11, 1931 CLAUDE C. BENNETT, OI SEATTLE, WASHINGTON, ASSIGNOR TO A. E. TERAGEN, 1110.,

OF SEATTLE, WASHINGTON, A. CORPORATION OF WASHINGTON AXLE PRESS Application filed June 25,

My invention relates to axle pres ses,-that is, to machines or tools for bending axles, bars, and various heavy metal members. It

- is of particular value in the adjustmentor alignment of vehicle wheels and axles,.and will hereafter be described in connection with such uses. This application is a continuation in part of my applications Serial Nos. 337,625 and 337,626, filed February 5, 1929.

It is an object of my invention to provide a simple means, easily attached to the axle, whereby a bend may be produced therein quickly and easily, as for instance, by the use of a hydraulic jac v It is a further object to provide. a device of this type, wherein the point or points of application of the force can be better controlled and fixed definitely, and in which the :0 members emplo, ed may not move relatively to one another uring the bending operation, and as a result of the forces generated at such a time. i

It is a further object to provide a device e which is simple in construction, and whic while stout enough ,to perform the. bendingoperation on heav axles, is made in parts which are light enoug .to be handled without difficulty, and to be put into operw It is a further object tov provide such a device which is adaptable to axles of various cross-sections and heights. f

Other objects, and more particularly such as pertain to the purely mechanical details of my invention, Wlll be. ascertained-best from "a study of the attached drawings, wherein my invention is shown in present preferred forms, of the specification,- wherein my invention in its'generic form and modifications is described, and of the appended claims, where-- in my invention and different species thereof are particularly defined. Figure 1 is a front e mobile axle, showing one formof my device in operative position suspended therefrom.

Figure 2 is a like view, showing a different form of my invention in operatlve position thereupon. p g Figure .3 is a similar view, showingoneof v the elements of my device of the clevis 3 over t levation of an automeans are provided against which one end-0f a jack member, such as the hydraulic jack 5,

associated with a different style of'axle.

Figure 4 IS a transverse section on line H of Figure 1. Figure 5 is a similar tra the line 55 of Figure 2.

Figure 6 is a similar cross-section on line 6-6 of Figure 3; V, Essentially, the bending is accomplished by. means of a bending lever 1, which is angular in form, comprising the horizontal arm or shelf 10, andthe depending arm 11. As

nsvers'e section on a pivot upon which the lever is supported, I

may provide a pin 2, which preferably is removably received in a corresponding transverse bore at the bend of the lever 1. ,The lever is supported suitably in operative position beneath the axle A, and in order to hold the'axle down to the lever 1, itisconvenient I to support the lever by a clevis 3 straddling the axle-and resting upon its upper edge, which clevis likewise has a bore to receive the pin 2. Thus, the supporting of the lever 1 upon the axle A requires only the slippinghe axle, and then the fitting 'of the lever into place, whereupon the pin- 2 is inserted through the bores in the lever and clevis. Since axles will vary in depth, I" provide a transverse groo ve 12 on the shelf or horizontal arm'lO, and in this may be received hardened bearing blocks 4. One or more of these may be employedas giay be found necessary, and these bear against the under side of the axle, slightly spaced vertically frointhe clevis 3; Also, the surface of these bearing blocks, which engages the axle, maybe shaped to fit the underside of. the axle, as for instance, inFigures 3 and 6, where p it is'shown as rounded tor'fit atubular axle. In such a case as this, it maybe found desirableto employ other bearing blocks .40 as adapters between the clevis 3 and the upper side of the axle A. Y p f At the lower end of the'dependingarm 11,

may bear. I prefer that the lower end of the lever be bifurcated, and that a cross-pin 15' be provided, preferably as an integral part of the lever, extending between the two sidno pins, and may, if desired, be made removable,

of the lower arm 11, and that the ack be provided at its base, and preferably at the end of its plunger also, with a hooked end, indicated at and 51 respectively. Cooperating with the cross-pin 15 is a second crosspin 15, which may be suitably supported or held relative to the cross-pin 15, and the jack is supported between these two cross-pins by engaging the respective hooked ends 50 and 51 therewith, whereupon, in the form shown in Figure 1, operation of the jack causes its extension in length and a forcing apart of the two cross-pins, with a consequent upward pressure upon the bearing blocks, this upward pressure being resisted by the clevis 3.

It will be understood that the resisting member 15 may well be either fixed in position or suspended in some way from the axle. It may also be the cross-pin of another bending lever unit, similar in all respects to.the

first, and suspended from the axle. In such an instance, as shown in Figure 1, there is an upward pressure upon the axle at the end ofeach of the horizontal arms 10.

This outward pressure of the jack at times causes a tendency for the bending levers to slide along the axle, and in order to hold them fixed imposition, I provide bars 6, which are secured upon the pivot pins 2, these pins extending through the bars. These bars preyent any separation of the pivot'pins, and consequently, maintain the pivots of the companion bending levers fixed relative to one another, still permitting the ends of the depending arms to be separated in the form shown in Figure 1. I

In Figure2 is shown a-modified form involving the'same bending levers, but permitting the horizontal arms 10 to be turned in-' wardly. In this case, it is necessar that the ends of the dependings arms be gether, and for this 'purpose, I may employ links 7, which are apertured to be su ported upon trunnions 17 and 17 which pro ect out wardl from the end of the depending arm 11. T ese may be formed as part of the cross although this is not necessary. The links 7 are slotted, as indicated at 70, and whereas one end of the links is pivotally secured to-the end of one lever, the trunnions 17 of the other lever are received in the slots 70. At

. the end of the links 7, projecting be 0nd the bending levers, they are connected y a secing levers together, the links being supported by engagement of the trunnions 17 in the slots 70. In this case, it will be found desirable to employ a bar 6 to prevent approach of the pivot pins 2.

Bars of various lengths would be employed to permit the location of the bending arms at rawn tosuch spacings as may be found desirable. Whereas in the drawings cotter pins are shown to hold the pivot pins 2 in place, to hold the cross-pin 71 in place, and to hold the links 7 upon the trunnions 17 and 17 it is not essential that they be employed, and in ractice they would seldom be used.
